A Linguistics Workbook, 4th Edition

Questions

A. What environment conditions the occurrence of the sounds $ and d? That is,

describe the phonological environments by listing the sounds whose occurrence

is associated with the derived consonants and d.

B. What distinctive features uniquely describe the natural class of sounds that

condition the change of S to s and r to d?

C. Given the rule schema A B / CD (see rule 3 in appendix l), state the

rule for the occurrence of and d in Tohono O'odham. The change of S and r

to ; and d may be stated in terms of segments, as shown below; but the

conditioning environment should be stated in terms of distinctive features. C

and D in the schema are "placeholders" (variables). In any actual rule that

conforms to the schema A + B / CD, one or the other of C and D may

be empty. That is, the change from S and r to and d may be conditioned

(1) by something that occurs before S and r and something that occurs after

(C and D), (2) by something that occurs before S and r (C only), or (3) by

something that occurs after S and r (D only).
